MUMBAI, India, Jan. 7 -- Intellectual Property India has published a patent application (202511103785 A) filed by Manipal University, Jaipur, Rajasthan, on Oct. 28, 2025, for 'an ai-driven automatic number plate recognition system.'
Inventor(s) include Mr. Pranav Kumar; Dr. Bhawana Sharma; and Dr. Lokesh Sharma.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to an AI-driven Automatic Number Plate Recognition (ANPR) system. The system comprises an image acquisition module that captures vehicle images from camera feeds or uploaded sources, followed by a multistage image preprocessing pipeline incorporating noise reduction, normalization, Contrast Limited Adaptive Histogram Equalization (CLAHE), and adaptive thresholding to enhance plate visibility in diverse lighting and noise conditions. A trained model localizes the license plate and recognise through a dual-model CNN architecture for general classification and another for resolving ambiguous character pairs such as 'O' and '0'. Post-processing with OCR correction and pattern matching validates results against regional plate formats. The recognized number is cross-checked with a connected vehicle database containing registration details and status flags. A web-based module displays vehicle information and triggers visual or audio alerts for flagged vehicles, enabling efficient real-time verification for law enforcement and smart city surveillance systems."
